The medium for all my 40 little plants is the same
prepared coco coir bought in home depot with fresh worm casting and perlite, only 2 had this problem

I'm using ro water and sometimes I feed with seeaweed extract and molasses in a ratio of quarter of the recomended.

not sure what's that

Looks like a bacterial/fungal spot disease......serenade is a good product to help protect from spores entering the stomata.

Its a bacilus strain.
